TROPICAL STORM LORENA DISCUSSION NUMBER 4
NATIONAL WEATHER SERVICE MIAMI FL
2 PM PDT TUE OCT 02 2001
VISIBLE SATELLITE IMAGES SHOW THAT THE ORGANIZATION OF THE STORM
CONTINUES TO SLOWLY IMPROVE...ALTHOUGH BANDING FEATURES ARE NOT YET
VERY WELL-DEFINED. DVORAK T-NUMBERS ARE 2.5 AND 3.0 FROM SAB AND
TAFB RESPECTIVELY. THE CURRENT INTENSITY ESTIMATE IS THE AVERAGE OF
THESE DVORAK ESTIMATES. UPPER-LEVEL OUTFLOW IS STILL BEING BLUNTED
A BIT ON THE NORTHWEST SIDE OF THE SYSTEM...BUT THE ENVIRONMENT
LOOKS FAVORABLE FOR SOME STRENGTHENING IN THE EARLY PART OF THE
FORECAST PERIOD.
THERE HAS BEEN LITTLE CHANGE TO THE FORECAST TRACK PHILOSOPHY. THE
OFFICIAL TRACK UPDATES THE PREVIOUS ADVISORY...AND IS CLOSE TO THE
UKMET/NOGAPS/AVN CONSENSUS. THE AVN CONTINUES TO SHOW A SHARPER
RECURVATURE THAN EITHER THE NOGAPS OR UKMET.
